Wow, thanks for all the information. Thanks Bruce Griffiths, the LTC6957 is expensive but looks very good for sine to square wave conversion.
Thanks Lester Veenstra for the details on some of the devices on the interface PCA and the link to the TLV3501 signal conditioning module. Thanks Bob kb8tq for the info and comments to each question. Glenn Little WB4UIV, I think that I might recover and reuse the OCXO connector from the interface PCAs. If you are still interested I can send you the PCAs minus those connectors for the cost of the postage, email me directly. Thanks Dave M for the detailed part number references. Thanks Ed Breya, Dan Rae and Charles Steinmetz. Useful to know where the interface PCA and OCXO were originally from and where more info can be found. Thanks Steve Longcor for digging up the interface PCA schematic. Looks like I have a bit of reading, designing and building to do now. :-) Cheers -- Manfred VK3AES _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
